Abstract
Current preserving services in the tropical mountain forest of Southern Ecuador are discussed, with a focus on arbuscular mycorrhizal (AM) fungi, microarthropods (oribatid mites), and protists (testate amoebae). Diversity patterns of AM fungi are described in a comparison of native forest with its anthropogenic replacement system of low plant diversity, while patterns of oribatid mites and testate amoebae are reported along an elevational gradient. Levels of AM fungal richness observed thus far were relatively high on both sites, but not unusually so. Belowground invertebrate richness did not approach that of aboveground invertebrates. Testate amoebae species numbers were relatively high overall, but did not follow a clear altitudinal gradient, in contrast to plant richness and oribatid mites. These results illustrate the complexity of the studied system in Ecuador with respect to the overall compartmentalization of diversity patterns.
